34Claims.

This invention relates to an improvement in scrap bunch cigar machines,its main object being the production of a machine specially adapted forlarge scrap tobacco, the machine herein described consisting of astationary magazine or hopper with intermittently revolving agitators,an oscillating transfer drum with a reciprocating tobacco pan, ameasuring chamber having gates which open automatically to admit thetobacco delivered by the pan, a chargecompressing and measuring unitwith automatic knock-cut device, a charge-cutting and transfer unit, anda charge-rolling and ejecting unit. With this and other objects notspecifically mentioned in view, the invention consists in certainconstructions and combinations hereinafter fully described and thenspecifically set forth in the claims hereunto appended.

The scrap tobacco is placed in the hopper in which it is kept in loosecondition by intermittently revolving agitators. Below the outlet of thehopper is placed an oscillating transfer drum in which a slidable pan issupported on a camoperated arm. In each cycle of the machine, this drummakes one-half revolution and returns to starting position. While in thestarting position, the pan ascends into the hopper and returns with aquantity of tobacco, the cam-operated knives provided on the pan beingopen during the ascent, and closing on reaching its uppermost positionto separate the quantity of the tobacco in the pan from the mass oftobacco in the hopper. Upon the return of the pan, the transfer drumwith the filled pan makes its forward half-turn during which the kniveson the pan are opened by engagement with a stationary cam so that thecharge can drop into the measuring chamber below, the cam-operated gatesof the latter opening during the forward turn of the drum. While thedrum, with the knives on the pan still open, then returns to startingposition, the gates of the measuring chamber are closed and the freshlydeposited loose charge is compressed by a horizontally slidablespring-tensioned plunger to the proper density determined by theadjustment of the plunger spring. The pan is designed to hold slightlymore tobacco than is required for one cigar bunch, so that there is asurplus of tobacco present in the measuring chamber after the charge hasbeen severed. When this surplus to-' bacco has accumulated in sufficientquantity for another cigar bunch, the motion of the transfer drumis'automaticaliy stopped for one cycle of the machine by means oflinkage between the compressing plunger and a cam which operates theoscillating means of the transfer arm. This linkage requires a.predetermined minimum forward stroke of the plunger to actuate the saidcam; when the surplus tobacco accumulated in the measuring chamberprevents the plunger from reaching the end of its predetermined stroke,the transfer drum cam remains stationary and no more tobacco isdelivered to the measuring chamber during that cycle of the machine. Acharge of tobacco sufiicient for one cigar bunch is severed by acam-operated vertically reciprocating knife and is then carried downwardby a vertically reciprocating transfer plunger which finally expels it.Upon the return of the transfer plunger and the charge cutting knife, arolling pin adjustably carried by a swinging rolling arm rolls thecharge into a binder previously deposited on the apron and delivers itinto a holder at the end of the rolling table from which it is taken byan operator serving a nearby bunchshaping and wrapper-applying machine.

In carrying the invention into effect there is provided a hopper forholding a supply of scrap tobacco, a measuring chamber below the hopper,an oscillating transfer drum, a pan in said drum adapted to be projectedinto the hopper to receive a quantity of tobacco and retracted into thedrum with aid quantity. mechanism foroecillatingsaiddrumandactuating'saidpan to remove a quantity of tobacco from said hopper anddeliver it to the measuring chamber. means for compressing the tobaccoin said measuring chamber, means for rolling a charge of tobacco-- in abunch binder, means for cutting of! a charge from the tobacco in themeasuring chamber and delivering it to said rolling means. and meanscontrolled by the tobacco-compressing meansfor incapacitating saidmechanism if there is a quantity of tobacco sufficient for more than twobunch charges in the measuring chamber, and there after rehabilitatingsaid mechanism. In the best constructions contemplated the pan isprovided mechanism, and a cam piece connected to said lever fordisengaging the pawl means. These various means and parts may be widelyvaried in construction within the scope of the claims, for theparticular machine selected to illustrate the invention is but one ofmany possible concrete embodiments of the same. The invention,therefore, is not to be restricted to the specific construction shownand described.

Referring now to Figs. 1 and 2, the side frames ll, ii of the machinesupport a base or table II upon which are mounted pedestals l1, II, asupport block ll and a pedestal frame It. In the side frames II isjournaled the drive shaft 20 of the machine which is driven through aworm wheel reduction gearing 24 on a shaft 22 by a belt 23 from a motor24. The shaft II carries cams 2|, II and 21. The side frames II, inconjunction with a bearing 28 suspended from the base it. supports ashaft 2! on which the cam levers actuated by the cams II, 20 and 21 arefulcrumed.

The pedestals l1, l1 support the hopper II and carry a shaft ii on whichthe horizontal transfer drum 3! is fixed. The support block ll carriesthe measuring chamber 33 and the slide bar 34 for the charge-compressingplunger fl.

and on the pedestal frame I! is mounted the chamber 36, forming acontinuation of the meas-' uring chamber, and charge-cutting andvertical transfer plunger unit 31. To the-base It is attached therolling table it over which swings the rolling pin it which isadjustably carried by an arm 40 pivoted on a shaft ll supported by theside frames IS. A treadie II on a shaft 43 in .frames II, by means of anarm l4. connecting rod 4i and bell-crank lever 40, controls the mainclutch of the machine on shaft 22. s

The tobacco T in hopper 3. is kept in loose condition by agitating rodsll mounted in ablock 48 on a shaft 49 supported by the hopper. the

shaft It being intermittently driven from shaft II by means of sprocketsII andll and chain '2, the sprocket II being attached to shaft II by asuitable device, such as a ball clutch or a pawl and ratchet, not shown,was to turn in one direction only. The shaft II is alternately turnedone-half revolution forward and back by means of a gear I! engaging witha rack attached to a cam lever 85 pivoted on shaft 20 and engaging cam"by means of roller It. Fast on shaft Ii cases is the hubof the-drum IIspider ll turnably mounted pedestal l'i' animal's-commas estal II andeattending through a semi-circular slot ll infl tlie" head of drum 8!.within the drum carries a forked bracket Ii supporting a shaft "Jigs. 4and}.

Thepantlhasa pocket provided therein adapted toreceive a quantity of tobacco when the pan is projected into the hopper,The cover plates It, which are fixed on the top of the pan. preventtobacco on either side of .thepocket, from entering the space providedfor the travel of the knives l8. Pivoted on shaft II are arms l'lcarrying the knives ll for separating the quantity of tobacco in thepocket from the mass in the hopper, the arms 81 being normally heldclosed-by a spring is connecting the same. Each of the arms I! has alink ll pivoted to a pin H carrying a roller 12 adapted to engage with acam piece II on bracket I. In a slot of one of the side arms of scoop IIis pivoted a double lever ll tensioned by a leaf spring ll, one arm ofwhich lever engages with pin II when its other arm is arrested by a stopscrew II in a lug on one of the arms of splder ll. The shaft I. has acrank 11, Fig. 1, connected by arod ll to a cam lever ll fulcrumed onshaft fl and carrying a roller ll engaging with a track of cam II.

In the starting position of drum 3!, when the pan I in the drum isunderneath the hopper outlet, the cam lever it controls the crank 'll.thereby projecting the pan it into the hopper ll. As the pan reaches itsuppermost position in the hopper, the trip lever 14 is turned by e agingwith stop screws It, so that its trip arm rates the pin Ii and moves thelinks from ing of the scoop, the roller 12 engages with the cam piece IIwhich is so shaped that the pin II is thereby moved towards the centerof the drum to a point beyond the neutral position of the links ll, thusopening the knives as shown In dotted lines in Fig. l, the spring 69then holding them open during the return of the drum to startingposition.

In the dotted position referred to, the quantity of tobacco T carried bythe pan is dropped into the measiu'ing chamber It. the hinged gates 82of which havebeen raised during the transfer motionofthe pan by aconnecting rod 83 attached to can lever II, the said connecting rodmoving oneendof a double lever 04 fulcrumed in a-bearing bracket Ifastened to a cross-piece 8! on slide; bar N, the other end of lever 84being connected by a link I! to a slide ll guided by a bar-ll attachedby a cross bar 9. to slide bar- 34, the slide ll having links ll pivotedto the gate l2. (Bee Figs. 1, 2, 6 and 7.)

The loose quantity of tobacco T deposited by the pan into the measuringchamber 33, which is supported by the cross piece It and by the ledgerplate "attached to frame It, is compressed into the chamber 33. whichforms a continuation of the measuring chamber, by the plunger 33. Thelatter is attached to a rod 33 sliding in a lug 34 of slide 33 mountedon slide bar 34. A spring 33 on rod 33 bears against the end of plunger33 and is adjusted to the proper tension by a socket 31 adiustablyattached to a rod 33 carried by lug 34, the tension of spring 33regulating the density of the tobacco compressed by the plunger 33. Theslide 33 is connecteli by a link 33 to a cam lever I43 fulcrumed onshaft 23 and having a roller III in engagement with cam 21. With theabove construction for projecting the pan into the hopper and cuttingoff the quantity of tobacco in its pocket, there is no tendency for thetobacco to bridge over the hopper outlet and thus retard the delivery ofthe tobacco from the hopper, as in prior scrap tobacco feeds.Furthermore, any excessively large scraps projecting out from the pocketwill be severed, and therefore will not impede the turning of thetransfer drum in its housing.

In order to prevent scant charging of the cutting chamber in case thepan should fail to pick up a full charge, the feed is so arranged thatthere will always be a surplus of tobacco in the measuring chamber. Forthis purpose, the pocket in pan 33 is made to hold an excess of tobaccoover one bunch charge, and the stroke of the plunger 33 is adjusted tosuch a clearance from the chamber 33 as to require at least two bunchcharges of the proper density to fill said chamber and the clearancespace. Thus, after the charge in the chamber 33 has been severed, thereis still more than enough compressed tobacco T" left in the measuringchamber to again fill the cutting chamber. Therefore, even when the nextquantity of tobacco delivered by the pan happens to be scanty, therewill be a full bunch charge. If, on the other hand, the quantitlesdelivered are each in excess of a bunch charge, this surplus tobaccowill accumulate in the measuring chamber and from time to time willprevent the plunger 35 from reaching the end of its predeterminedstroke. At these times, a finger I32 attached to the end of rod 33 willfail to engage the trip lever I33 placed in its path, and thus will stopthe feed drum and scoop from operating during the next cycle of themachine so that then one charge from the pan is omitted and themeasuring chamber cleared from excessive tobacco accumulation.

The trip lever I33, Figs. 6 and 'I, is carried by a stud I44 in supportblock I3 on which it is held in engagement with a crank arm I33 by aspring I34. The arm I33 is connected by a cross-stud I31 and a rod I33to one end of a horizontal double lever I33, Figs. 1 and 2,-the otherend of which is held in engagementwith the end of a vertical doublelever III by means of springs III and H2. The levers I33 and III areiulcrumed on studs H3 and H4. respectively, in side frame II. The freeend of lever I I3 carrles a cam piece IIi having an upper and slower camsurface adapted to engage with the driving mechanism of cam 23 whichcontrols the motion of the feed drum rack 34 and of the pan-lever shaft33. The cam 23 is keyed on a sleeve Iii which rides loosely on shaft 23and has an arm II1 carrying'a pawl II3 engaging with ratchet II3 fasiaonshaft 23, the pawl III being held in engageinent by a spring I23. Thetooth end of pawl II3 carries a roller HI, and to the face of ratchet H3is pivoted a roller I22, both rollplates I33 and depress the ,slidesI34.

ers being in vertical alignment with the cam piece III.

The cam piece III is normally in the path of roller III. When theplunger 33 travels its full stroke, the finger I32 engages with thelever I33 and thereby trips the lever I33, allowing the spring III toturn the lever III and thus to bring the cam piece III out ofregistration with the path of roller I2I. The engagement of pawl I IIwith ratchet II3 then will not be disturbed, and the cam 23 will bedriven by the ratchet I I3. accumulated in the measuring chambershortens the stroke of plunger 33 so that the finger III2 will notengage with lever I33, the cam piece III will remain in its raisedposition and will cause the roller I2I to engage with it, therebylifting the pawl III out of mesh with the ratchet II3, thus releasingthe cam 23 and stopping the tobacco feed. Then when the finger I32engages with lever I33, on full stroke of plunger 33, and trips thelever I33, the spring II2 turns lever III to bring the cam piece out ofengagement with the roller I2I and restart the tobacco feed. Inthe-tripped position of lever I III, on full stroke of plunger 33, thecam piece H5 comes into registering position with roller I22 so that theturning of ratchet III will engage the roller with the cam piece andreset the lever IIII into tripping position against the end of the leverI33 for the next stroke of the plunger.

When the chamber 33 has been filled by the advance of plunger 33, thereciprocating vertical rod I23 descends, thereby operating thecharge-cutting knife I24 and the charge ejecting or transfer plunger 31.The rod I23 which slides in bearings of the pedestal frame I3, isactuated by a cam lever I25 fulcrumed on shaft 23 and having a rollerI26 in a track of cam 21.

To the slide rod I23, Figs. 8 to 12, is clamped a bracket I21 the freeend of which projects into an opening of a block I23 attached to slidesI23 and is amxed thereto by a vertical pin I3Il. The slides I23 whichare connected by a tie plate I3I carry the charge-cutting knife I24, thevertical position of which is adjusted by screws I32 held in block 23.The slides I23 fit into a recess of frame I3 in which they are guided byretaining strips I33. Into a recess of the knife slides I23 are fittedplunger slides I34 joined by a tie plate I35, and in the space betweenthe slides I34, the knife I24 and the tie plate I35, slides the verticalcharge ejecting plunger 31. Into slots provided in the latter projectstuds I33 carried by block I23 and engaging with pins I31 resting oncoil springs I33 inserted into vertical holes formed in the body of theplunger 31.

To the tops of slides I34 are attached plates I33 resting on coilsprings I43 held on blocks "I, attached to knife slides I23. In theupposition of rod I23, the springs I40 hold the plates I33 against studsI42 held in frame I3. To the tops of the knife slides I23 are fastenedplates I43 carrying adjustable set screws I44 which on the down-strokeof rod I23 engage the The plunger 31, in a top strip I43 attached to it,carries an adjusting screw I43 which rests on one arm of a bell-cranklever I41 pivoted on bracket I21 attached to rod I23. The other arm oflever I41 carries a cam roller I43 engaging with a stationary cam pieceI43 attached to frame I3.

To the bottom of the slide tie plate I3! is fastened the back of thechamber 33 in the sides of which, formed by the ends of slides I34, is

the chamber, Pi attached to slide To lugs of frame it is fastened theledger plate I! for the knife I24. The ledger plate, which ishorizontally adjustable by screws I. is hollowed out to receive thedelivery end of the measuring chamber II.

As the rod III descends, upon a charge having been delivered to thechamber I. the bracket I21 depresses the block III, thereby actuatingthe charge-cutting knife ill. During the descent of the knife, theplunger 11 is held in place by the springs I", the studs I80 depressingthe pins lll against the tension ofthe springs ill, thereby graduallycompressing the charge in the vertical direction while the same is beingout. As soon as the charge is severed. the set screws I come intoengagement with the plates ill, thereby depressing the plunger 11 andcutting chamber 36 against the premure of springs lllLthus transferringthe charge to the rollins apron below.

tion, thereby turning lever in upon which rests I the stop screw I ofthe plunger. The latter is then free to move downward in the slides I34due tothe stored-up tension of the springs Ill, and thus to expel thecharge from the chamber 30.

On the return stroke of rod Ill, the springs I, released by the ascentof the screws-l, raise the plunger fl, chamber 30 and knife I24 untilengagement of the plates I with the studs I42 takes place, whereupon theplunger and chamber ll 'are arrested and the knife ascends alone, theaccompanying ascent of the studs I" then permitting the' pins Ill torise, releasing the tension of the springs I. On the upward stroke ofthe slides 134, the cranks ill engage with the stops I53, therebyclosing the gate I" so that the chamber 36 is now ready to receive a newcharge.

The bunch charge B, Fig. 1,'-delivered by the plunger 31 onto therolling apron I" is rolled by the rolling pin 39 into a binder laid onthe apron by an operator, thereby forming the bunch B which at the endof the rolling pin stroke is delivered into a holder or clip I". Theapron I" is fastened to the forward end of table I. by a strip I" and isheld in proper tension by an apron-tightener arm I" which is pivoted onshaft 20 and actuated through a connecting rod in, a cam lever III and aroller Iii 'by cam 26. The portion of the apron "ion which the binder islaid. and the corresponding portion of table 38 which is hollow, areperforated and the table I8 is supplied with suction, from suitablemeans of well known construction not shown, which keeps the binder flaton the apron until it is rolled.

The rolling pin 39, Figs. 1. 2 and 3, is mounted in blocks I82 carriedby a yoke I" pivoted in a swingable bracket I which in turn is pivotedto the rolling arm 40. By this arrangement, the angle of the rolling pinI! can be readily adiusted for rolling straight as wellas taperedbunches of various shapes.
